Wildcat AH1 Helicopter

The Wildcat is a multi-role helicopter operated by Naval Air Squadron 847 (NAS 847) Commando Helicopter Force (CHF) and the Army Air Corps (AAC) Special Forces Wildcat flight.

The Wildcat is designed and manufactured by AgustaWestland, who sell it as the AW159 Wildcat. The new aircraft replaces the ageing fleets of Lynx helicopters in British military service. They began being entered into service in late 2014 / early 2015.

Both NAS 847 and the Army Air Corps field the AH1 variant of the Wildcat, which is designed as a battlefield reconnaissance, troop transport, airborne command post and force protection platform. The Royal Navy also fields the Wildcat HMA2 (Helicopter Maritime Attack Mk 2) variant in the anti-ship and anti-submarine role.

While it retains the basic underlying shape of the Lynx helicopters it replaces, the Wildcat AH1 features an array of sophisticated systems that result in a much more capable aircraft. These include:

  • 2 Light Helicopter Turbine Engine Company (LHTEC) CTS800-4N engines providing improved lift and performance, allowing for operation at high altitude and in hot conditions
  • full authority digital engine control (FADEC)
  • new 4-bladed tail rotor
  • crashworthy crew and passenger seating, armoured crew seating
  • role-fit armoured cabin floor
  • engine infrared suppression (IRS) system
  • a fully digital cockpit integrates core avionics, communications and navigation systems and includes:
    • 4 x Smiths Industries SDS-5000 10 inch x 8 inch LCD integrated display units (IDU)
    • Thales Avionics secure communications control system (SCCS) featuring VHF/UHF SATURN and HF radios and Bowman radio functionality
    • integrated global positioning system (GPS) inertial navigation system
    • mission planning system (MPS)
  • Nose-mounted L3 Wescam MX-15Di electro-optical laser designator turret

Wildcat AH1s are fitted with an advanced defensive countermeasures package, namely the Selex HIDAS 15 (Helicopter integrated defensive aids system).

  • Radar Warning Receiver and Defensive Aids System Controller
  • Missile Warning System
  • Countermeasures Dispensing System (chaff and flare launcher)
